Line #81 you are creating a new sub-form for each item. I changed it by a 'with h.div:' and added a submit button line #91 in https://gist.github.com/metaperl/e6fd793736f12656cd8b#comment-1437980 > 2.

Also you don’t need to define 'editor.Editor' sub-classes. Here is a simpler example without theses classes: https://gist.github.com/nagareproject/3984ff9d13616f85b908 Then you can change the checkboxes action to be an 'ajax.Update()' if you want it to be executed as soon as the checkbox is clicked: https://gist.github.com/nagareproject/6ea5eebffa93b199afde -- You received this message because you are subscribed to the Google Groups "Nagare users" group.
